Astera Labs (NASDAQ: ALAB) provides rack-scale AI infrastructure through purpose-built connectivity solutions. By collaborating with hyperscalers and ecosystem partners, Astera Labs enables organizations to unlock the full potential of modern AI. Astera Labs’ Intelligent Connectivity Platform integrates CXL®, Ethernet, NVLink, PCIe®, and UALink™ semiconductor-based technologies with the company’s COSMOS software suite to unify diverse components into cohesive, flexible systems that deliver end-to-end scale-up, and scale-out connectivity. The company’s custom connectivity solutions business complements its standards-based portfolio, enabling customers to deploy tailored architectures to meet their unique infrastructure requirements.
ABOUT THE ROLE
Astera Labs is seeking Firmware Engineers across multiple seniority levels to architect, develop, and deliver core firmware for our next-generation connectivity, chiplet, and system products. This is a catch-all requisition designed to hire exceptional firmware talent aligned to one or more critical technical domains across PCIe/CXL, Ethernet, UALink, UCIe/Chiplet, and Device Driver development. Firmware is a core differentiator for Astera Labs’ products and is treated as a first-class engineering discipline, on par with hardware and silicon design. Engineers in this role will work closely with Architecture, RTL, Physical Design, Validation, and Systems teams, and may be customer-facing to support integration, debug, and deployment in hyperscale and data-center environments. We are hiring Individual Contributors (Senior up to Senior Principal). This role is required onsite in San Jose, CA.
KEY RESPONSIBILITIES
- Architect, develop, and maintain bare-metal and low-level firmware running on embedded microcontrollers within Astera Labs SoCs and systems.
- Design and implement device drivers, core firmware services, and hardware abstraction layers for high-speed connectivity products.
- Define and implement HW-SW interfaces in close collaboration with RTL, PD, and Architecture teams.
- Lead bring-up, debug, and validation of firmware on silicon and system platforms.
- Develop and maintain C/C++ firmware codebases, SDKs, and supporting infrastructure.
- Build automation, tooling, and diagnostics using Python and scripting frameworks.
- Participate in system-level debug involving PCIe, Ethernet, memory subsystems, and interconnect fabrics.
- Support customer enablement, integration, and escalations as needed.
BASIC QUALIFICATIONS
- Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field (Master’s preferred).
- Strong fundamentals in embedded systems, computer architecture, and low-level software.
- Proven experience developing firmware for complex SoC or silicon-based products in Server, Storage, Networking, or Accelerator environments.
- Proficiency in C (required); C++ experience is a plus.
- Ability to work cross-functionally in a fast-paced, highly technical environment.
REQUIRED EXPERIENCE
- Bare-metal or RTOS-based firmware development (e.g., ThreadX, MQX, or equivalent).
- Firmware development for on-chip microcontrollers and supporting SDKs.
- Strong debugging skills across hardware, firmware, and system layers.
- Familiarity with firmware build systems and tooling (gcc, Make, Git, Doxygen).
- Python scripting for automation, validation, or tooling.
- Hands-on experience with server, storage, or networking systems.
PREFERRED EXPERIENCE / NICE TO HAVE
- Firmware development for PCIe or Ethernet switch products.
- Exposure to BMCs, OpenBMC, or system management firmware.
- Experience with high-speed interfaces such as:
- PCIe (Gen3+)
- Ethernet (100G / 400G+)
- DDR, NVMe, USB, Infiniband
- Participation in industry forums or ecosystems (e.g., OCP, OpenBMC).
- Customer-facing or field-enablement experience.
COMPENSATION
- The base salary range is $135,000–$255,000 USD for Senior through Senior Principal roles. Your base salary will be determined based on your location, experience, and the pay of employees in similar positions.
We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.

Get Access To All JobsTips for Finding Senior Software Engineering Jobs at Astera Labs Jobs
Frame your systems experience for silicon-adjacent roles
Astera Labs builds PCIe, CXL, and Ethernet connectivity silicon. Tailor your resume to highlight firmware, driver development, or hardware-software integration work. Generic software engineering experience reads as a weaker fit than demonstrated knowledge of low-level systems or network stack development.
Target roles explicitly listing hardware-software co-design
Astera Labs' engineering roles frequently sit at the boundary of software and silicon. Job postings that mention firmware, PCIe validation, or SDK development signal the clearest sponsorship pathway, since those functions align with the specialty occupation standard USCIS applies to H-1B petitions.
Align your offer timeline with H-1B cap deadlines
If you need cap-subject H-1B sponsorship, USCIS registration opens in March for an October 1 start date. Negotiate your offer or start date with Astera Labs' recruiting team so the petition can be filed during the April filing window without gaps in your authorization.
Use Migrate Mate to surface open Senior Software Engineering roles at Astera Labs
Sponsorship-eligible roles at semiconductor and connectivity hardware companies aren't always labeled clearly on general job boards. Migrate Mate filters specifically for visa-sponsoring employers in this space, so you can find and track Astera Labs openings without manually screening hundreds of postings.
Request clarity on PERM timing for Green Card pathways
EB-2 and EB-3 PERM labor certification at the DOL can take over a year before an I-140 is even filed. Ask your recruiter early whether Astera Labs initiates PERM during your first H-1B period, since Indian-born engineers face long priority date backlogs that make early filing critical.

Find Senior Software Engineering at Astera Labs JobsFrequently Asked Questions
Does Astera Labs sponsor H-1B visas for Senior Software Engineers?
Yes, Astera Labs sponsors H-1B visas for Senior Software Engineering roles. As a company in the semiconductor connectivity space, they regularly hire specialized engineering talent that qualifies under the H-1B specialty occupation standard. If you're subject to the H-1B cap, sponsorship would align with the annual March registration and October 1 start date cycle.
Which visa types does Astera Labs commonly sponsor for Senior Software Engineering roles?
Astera Labs sponsors H-1B, TN, and F-1 OPT for Senior Software Engineering positions, and supports Green Card pathways through EB-2 and EB-3. TN is available to Canadian and Mexican nationals in qualifying engineering roles. F-1 OPT candidates should confirm E-Verify enrollment to ensure STEM extension eligibility before accepting an offer.
What qualifications does Astera Labs expect for Senior Software Engineering roles?
Astera Labs' Senior Software Engineering roles typically require a bachelor's or master's degree in computer engineering, electrical engineering, or computer science, combined with hands-on experience in systems software, firmware, or hardware-software integration. Familiarity with PCIe, CXL, or high-speed connectivity protocols is a genuine differentiator given the company's product focus.
How do I apply for Senior Software Engineering jobs at Astera Labs?
You can apply directly through Astera Labs' careers page or find their open Senior Software Engineering roles on Migrate Mate, which filters specifically for visa-sponsoring employers. When applying, align your application materials to their connectivity silicon focus and be upfront about your visa status and required sponsorship type so recruiters can assess your timeline accurately.
How long does the visa sponsorship process take for a Senior Software Engineering role at Astera Labs?
Timeline depends on your visa type. H-1B cap cases require USCIS registration in March and carry an October 1 start date, meaning roughly six months from registration to authorization. TN processing at the border or consulate can be faster. Green Card sponsorship via PERM and I-140 typically spans two or more years, so starting that conversation early in your employment matters significantly.
